Résumé

The author previously developed a theoretical envelope model for bubbles condensing in immiscible liquids. The envelope model defines two zones while condensing. In the first zone the bubble accelerates after detachment from the nozzle and the heat is transferred through a viscous boundary layer at the front of the bubble and through the wake at the rear. In the second zone the bubble decelerates, settles into the wake and the heat is transferred through the wake all around the bubble. In a third zone, the bubble reaches the terminal velocity while the condensation process is terminated. In this article, both models were modified to suit bubble condensing in miscible liquids. The experimental results for freon-113 bubbles condensing in subcooled freon-113 are presented.
